BEST: Selena Gomez In Givenchy(01 of31)
Open Image ModalRed hot! Selena Gomez stunned on the red carpet wearing a deep ruby sequinned dress, complete with a modest slit at the centre. Paired with that slicked down hair and red eyeshadow (!!!), Gomez looks like a true siren. (credit:Jason Merritt via Getty Images)

Open Image ModalWORST: Fifth Harmony(05 of31)
Open Image ModalThe girls just don't look like a cohesive group in their respective ensembles. (credit:Mike Windle/AMA2015 via Getty Images)
BEST: DNCE(06 of31)
Open Image ModalThese outfits are daring, and that's why we love them. Cole Whittle rocked a man skirt and turtleneck like a pro, while Joe looked slick in his burgundy leather jacket and matching pants. JinJoo Lee's knit ensemble is adorable and Jack Lawless looks like the cool rocker he is. Also, can we just talk about how they all match perfectly, while still maintaining their individual styles? Now THAT is how a group should dress. (credit:Mike Windle/AMA2015 via Getty Images)
ON THE FENCE: Nick Jonas In Topman(07 of31)
Open Image ModalCons: too much tone-on-tone. Pro: Turtleneck Drake vibes. (credit:Mark Davis via Getty Images)
BEST: Kendall Jenner In Oriett Domenech(08 of31)
Open Image ModalHot dress? Check. Sexy shoes? Check. Killer hairstyle? Check. Safe to say Kendall nailed it. (credit:Mark Davis via Getty Images)
WORST: Kylie Jenner In Custom Bryan Hearns(09 of31)
Open Image ModalBEST: Zendaya In Emanuel Ungaro(10 of31)
Open Image ModalWORST: Gwen Stefani In Yousef Al-Jasmi(11 of31)
Open Image ModalOh Gwen. We're usually HUGE fans of "The Voice" judge's style, but this is just bizarre. From the sheer skirt to the voluminous top, this outfit is just bad. Her hair and makeup though? Flawless, as usual. (credit:Kevin Mazur/AMA2015 via Getty Images)
WORST: Justin Bieber In Fear of God And Amiri(12 of31)
Open Image ModalNo Justin, just no. You could have done so. Much. Better. Is it too late now to say sorry, we don't like this look? (credit:Michael Kovac/AMA2015 via Getty Images)
BEST: Demi Lovato In Lorena Sarbu(13 of31)
Open Image ModalDemi Lovato took it back to the roaring '20s in her printed gown. The print makes it modern, while those finger waves and dark makeup make for a gorgeous, flapper look. (credit:Steve Granitz via Getty Images)
WORST: Tove Lo In Lamija Suljevic(14 of31)
Open Image ModalWORST: Carrie Underwood In Elie Madi(15 of31)
Open Image ModalSorry Carrie, but this just isn't cutting it for us, especially with that glittery cape. (credit:Jeff Kravitz/AMA2015 via Getty Images)
BEST: Ciara In Reem Acra(16 of31)
Open Image ModalThis gown hugs Ciara's figure perfectly and looks almost painted onto her body. (credit:Mark Davis via Getty Images)
WORST: Kat Graham In Georges Chakra(17 of31)
Open Image ModalWhile the gown itself is quite lovely, it's just not flattering on Kat Graham. Also seems a bit much for this red carpet, no? (credit:Jason Merritt via Getty Images)
ON THE FENCE: One Direction(18 of31)
Open Image ModalLouis, Liam and Niall all look rather dapper, while Harry seems to stand out...we're just not quite sure if he does in a good way. (credit:Kevin Mazur/AMA2015 via Getty Images)
BEST: Shawn Mendes(19 of31)
Open Image ModalSimple, yet stylish. (credit:Frazer Harrison/AMA2015 via Getty Images)

Open Image ModalGolden goddess. (credit:Jeff Kravitz/AMA2015 via Getty Images)
ON THE FENCE: Nina Dobrev(21 of31)
Open Image ModalWe love this floral theme going on here. Our only complaint? Those shoes. (credit:Kevin Mazur/AMA2015 via Getty Images)
WORST: Ellie Goulding In Alexandre Vauthier Haute Couture(22 of31)
Open Image ModalThis dress seems a bit dated, no? More early 2000s than 2015. (credit:Mike Windle/AMA2015 via Getty Images)
ON THE FENCE: Hannah Davis In Naeem Khan(23 of31)
Open Image ModalThis reminds us of a modern, sexy Joan of Arc. (credit:Mark Davis via Getty Images)
BEST: Ashley Benson In Max Azria Atelier(24 of31)
Open Image ModalWorking that pantsuit like a BOSS. (credit:Frazer Harrison/AMA2015 via Getty Images)
BEST: Meghan Trainor(25 of31)
Open Image ModalGlam, in an understated way. We love. (credit:Mark Davis via Getty Images)
WORST: Alanis Morisette(26 of31)
Open Image ModalWe hate to put Alanis on the worst dressed list, but this outfit just doesn't work. That leather turtleneck just looks uncomfortable and is oddly paired with that high-waisted maxi skirt. (credit:Mike Windle/AMA2015 via Getty Images)
BEST: Julianne Hough In Zuhair Murad(27 of31)
Open Image ModalBEST: Rebel Wilson(28 of31)
Open Image ModalLooking like a space goddess! (credit:Mark Davis via Getty Images)

Open Image ModalTOTAL '90s vibes going on here and we LOVE it. (credit:Frazer Harrison/AMA2015 via Getty Images)
BEST: Hailee Steinfeld In Zuhair Murad(30 of31)
Open Image ModalThis jumpsuit is fierce. From the low V-neck to the figure-hugging silhouette, Hailee is killin' it. (credit:Michael Kovac/AMA2015 via Getty Images)
ON THE FENCE: Paula Abdul(31 of31)
Open Image ModalSparkle overload! But Paula still looks stunning. (credit:John Sciulli/AMA2015 via Getty Images)
